An Aeroflot flight from Hong Kong believed to be carrying Edward Snowden landed in Moscow. Russia’s state ITAR-Tass news agency cited an unnamed Aeroflot airline official as saying Snowden was on Flight SU213, which landed on Sunday afternoon in Moscow. The report said he intended to fly to Cuba on Monday and then on to Caracas, Venezuela.

As CBS 2’s Dave Carlin reported, Snowden managed to get in the plane despite an enormous effort underway to return him to the U.S. to face espionage charges.

And in the wake of Snowden’s escape, a Cold War-era drama has begun playing out at the Moscow airport hotel where he is staying. The 29-year-old high school dropout and failed male model is now one of the most famous faces, and most wanted people, in the world.

“I think the chase is on,” said U.S. Sen. Dianne Feinstein (D-Calif.)

Snowden had been in hiding in Hong Kong for several weeks since he revealed information on the highly classified spy programs. The WikiLeaks anti-secrecy group said it was working with him and he was bound for an unnamed “democratic nation via a safe route for the purpose of asylum.”

On Sunday afternoon, WikiLeaks said Snowden was going to Ecuador, not Venezuela, to seek asylum.

The group said in a statement Sunday that Edward Snowden is “bound for the Republic of Ecuador via a safe route for the purposes of asylum, and is being escorted by diplomats and legal advisors from WikiLeaks.”

Lawmakers on both sides of the aisle said Snowden needs to be brought to justice.

“I hope we chase them to the ends of the earth, bring him to justice, and let Russia know there will be consequences if they harbor this guy,” said U.S. Sen. Lindsey Graham (R-S.C.)

“I want to get him caught and brought back for trial,” added Feinstein.

And as CBS 2’s Cindy Hsu reported, U.S. Sen. Charles Schumer (D-N.Y.) expressed anger at the Kremlin for allowing Snowden into Russia.

“Putin never hesitates to put a finger in the eye of the United States — whether it is Syria, Iran, and now, of course, with Snowden,” Schumer said. “That’s not how allies should treat one another, and I think it will have serious effects for the United States-Russia relationship.”

The White House had no immediate comment about the departure, which came a day after the United States made a formal request for his extradition and gave a pointed warning to Hong Kong against delaying the process of returning him to face trial in the U.S.

The Department of Justice said only that it would “continue to discuss this matter with Hong Kong and pursue relevant law enforcement cooperation with other countries where Mr. Snowden may be attempting to travel.”

Snowden was the Hawaii-based contract analyst for the NSA who has been on the run since he leaked details of secret U.S. government surveillance programs used in the war on terror.

“The greatest fear I have regarding the outcome of these disclosures is nothing will change,” he said in an interview with The Guardian newspaper in the U.K.

“This was an individual with top-secret clearance, whose duty it was to administer these networks,” said NSA Director Gen. Keith Alexander. “He betrayed that confidence and stole some of our secrets.”

Snowden’s passport is now revoked, which means he will have to be granted asylum. The U.S. State Department will put intense pressure on any country trying to host Snowden.

The Hong Kong government said in a statement that Snowden left “on his own accord for a third country through a lawful and normal channel.”

It acknowledged the U.S. extradition request, but said U.S. documentation did not “fully comply with the legal requirements under Hong Kong law.” It said additional information was requested from Washington, but since the Hong Kong government “has yet to have sufficient information to process the request for provisional warrant of arrest, there is no legal basis to restrict Mr. Snowden from leaving Hong Kong.”

The statement said Hong Kong had informed the U.S. of Snowden’s departure. It added that it wanted more information about alleged hacking of computer systems in Hong Kong by U.S. government agencies which Snowden had revealed.

The signal that Hong Kong had let Snowden go on a technicality appears to be a pragmatic decision aimed at avoiding a drawn out extradition battle. The move swiftly eliminates a geopolitical headache that could have left it facing pressure from both Washington and Beijing.

Hong Kong, a former British colony, has a high degree of autonomy and is granted rights and freedoms not seen on mainland China, but under the city’s mini-constitution, Beijing is allowed to intervene in matters involving defense and diplomatic affairs.

Hong Kong has an extradition treaty with the U.S., but the document has some exceptions, including for crimes deemed political.

“China clearly had a role in this,” Feinstein said. “It wasn’t just Hong Kong.”

Russian officials have given no indication that they have any interest in detaining Snowden or any grounds to do so. Foreign Minister Sergey Lavrov has said that Russia would be willing to consider granting asylum if Snowden were to make such a request.

Russia and the United States have no extradition treaty that would oblige Russia to hand over a U.S. citizen at Washington’s request.

WikiLeaks said it was providing legal help to Snowden at his request and that he was being escorted by diplomats and legal advisors from the group. Its founder, Julian Assange, who has spent a year inside the Ecuadorean Embassy in London to avoid extradition to Sweden to face questioning about sex crime allegations, told the Sydney Morning Herald that his organization is in a position to help because it has expertise in international asylum and extradition law.

The Obama administration on Saturday warned Hong Kong against delaying Snowden’s extradition, with White House national security adviser Tom Donilon saying in an interview with CBS News, “Hong Kong has been a historically good partner of the United States in law enforcement matters, and we expect them to comply with the treaty in this case.”

Snowden’s departure came as the South China Morning Post released new allegations from Snowden that U.S. hacking targets in China included the nation’s cellphone companies and two universities hosting extensive Internet traffic hubs.

He told the newspaper that “the NSA does all kinds of things like hack Chinese cellphone companies to steal all of your SMS data.” It added that Snowden said he had documents to support the hacking allegations, but the report did not identify the documents. It said he spoke to the newspaper in a June 12 interview.

With a population of more than 1.3 billion, China has massive cellphone companies. China Mobile is the world’s largest mobile network carrier with 735 million subscribers, followed by China Unicom with 258 million users and China Telecom with 172 million users.

Snowden said Tsinghua University in Beijing and Chinese University in Hong Kong, home of some of the country’s major Internet traffic hubs, were targets of extensive hacking by U.S. spies this year. He said the NSA was focusing on so-called “network backbones” in China, through which enormous amounts of Internet data passes.

The Chinese government has not commented on the extradition request and Snowden’s departure, but its state-run media have used Snowden’s allegations to poke back at Washington after the U.S. had spent the past several months pressuring China on its international spying operations.

A commentary published Sunday by the official Xinhua News Agency said Snowden’s disclosures of U.S. spying activities in China have “put Washington in a really awkward situation.”

“Washington should come clean about its record first. It owes — an explanation to China and other countries it has allegedly spied on,” it said. “It has to share with the world the range, extent and intent of its clandestine hacking programs.”
